Windows XP and was using Firefox latest release or whatever. Now when I click on the icons on my desk top nothing happens, zilch etc. Got here by using IE and the search facility on it. Any ideas what's wrong and how to correct it. I've tried a system restore, back a week, but same problem. I've run Ad Aware, Spybot and AVG but the only thing that turns up is the Java/Byte/Verify virus thing. Which I don't know how to delete. And PC sounds like it's working flat out.
